摘要： In the Local Storage (18), a plurality of files, merge management information which specifies a file out of the plurality of files to be used in combination with what is recorded on a Read-Only recording medium, and signature information used for judging the authenticity of the merge management information. The Virtual File System unit (38) judges the authenticity of the merge management information based on the signature information. In the case where the merge management information is judged to be authentic, the Virtual File System unit (38) generates package information which indicates a new file structure obtained by adding the file specified by the merge management information to the file structure of the Read-Only recording medium.

摘要： A playback apparatus plays back video data recorded on a recording medium such as a BD-ROM. The playback apparatus includes an interface in which a removable medium such as an SDRAM can be inserted, a detection module that detects that the removable medium is inserted, and a virtual file system. The virtual file system is used if the removable medium is detected to be inserted, if additional content such as subtitles is recorded on the removable medium, and furthermore if the additional content is associated with the video data recorded on the BD-ROM, etc. The virtual file system is used for dynamically combining the video data recorded on the BD-ROM, etc. and the additional content of the removable medium so as to play back a virtual package.

摘要： A playback device plays back a digital stream and executes an application. A Java™ module is a platform unit, executes the application, and performs playback control based on a result of the execution. When performing this playback, the playback device has a plurality of real parameters specific to the playback device, for the playback control. The Java™ module provides a function using a real parameter to the application, in response to a method call from the application.

摘要： A playback apparatus for playing a digital stream in conjunction with an application includes a package management unit operable to generate package information by merging files recorded on a first recording medium and a second recording medium, in accordance with merge management information, and a selection unit operable to detect a plurality of playable titles from the package information, and select one of the detected titles as a current title. After the application requests the package management unit to update the merge management information, by specifying new merge management information, the package management unit changes a file referenced from the newly specified merge management information to read-only before updating the package information, and at a point at which digital stream playback stops due to a current title change by the selection unit, the package management unit generates new package information by combining files recorded on the first and second recording media, in accordance with the newly specified merge management information.

摘要： An integrated circuit stores a module that executes applications that play digital streams. When the module is executed, the integrated circuit generates package information by merging files recorded on a first recording medium and a second recording medium, in accordance with merge management information, detects a plurality of playable titles from the package information, and selects one of the detected titles as a current title. The integrated circuit executes the application associated with the current title, and the executed application makes a request to update the generated package information by specifying new merge management information. The integrated circuit changes a file referenced from the newly specified merge management information to read-only before updating the package information, and at a point at which digital stream playback stops due to a current title change, the integrated circuit generates new package information by combining files recorded on the first and second recording media, in accordance with the newly specified merge management information.
